PROBLEM TO BE SOLVED: To provide a water supply device for a cultivation container with which a small amount of water automatically and continuously drops into soil in a cultivation container to make water supply.SOLUTION: The water supply device is structured as follows: a pressing roller 12 of a flow rate adjusting part 7 appropriately turns and slides upward/downward to adjust compressing force pressing a water supply tube 6 against the back surface plate 13 of a case 11 the flow rate of water dropping into an accumulation part 22 of a dropping part 8 is adjusted to be set so that water at a prescribed flow rate may flow down to the accumulation part 22 the water at the prescribed flow rate may flow down to the accumulation part 22 and accumulate in a part lower than a water introduction opening 27 at the lower part of the accumulation part 22 and, when gradually-accumulated water 3 gets to a water level upper than the water introduction opening 27, the gradually-accumulated water 3 may flow into the water introduction opening 27 and automatically and continuously drop into the soil 4 so as to be supplied.COPYRIGHT: (C)2013,JPO&INPIT【課題】栽培容器の土壌中に、僅かな量の水を自動的に継続して滴下するようにして給水する。【解決手段】流量調整部7の押圧ローラ12を適宜回動して上・下方へスライドさせることにより、給水チューブ6をケース11の背面板13に押し付ける圧縮力を調整し、滴下部8の滞留部22へ滴下する水の流量を調整して、所定の流量の水が滞留部22へ流下するよう設定し、且つ前記所定流量の水が滞留部22へ流下して、該滞留部22の下方部の水導入口27より下方に滞留し、そして徐々に滞留して行く水3が、前記水導入口27より上方に水位に達したときに、該水導入口27に水3が流入して自動的に継続して土壌4中に滴下するようにして給水できるよう構成する。【選択図】図1
